Role-Based Access Control Should Be Used on Kubernetes Services

Description:

To provide granular filtering on the actions that users can perform, use Role-Based Access Control (RBAC) to manage permissions in Kubernetes Service Clusters and configure relevant authorization policies. 

Solution/Reference: 

To Use Role-Based Access Control (RBAC) you must recreate your Kubernetes Service cluster and enable RBAC during the creation process. Creating a Kubernetes Service with RBAC enabled can be done via the portal as follows:
1. Go to Azure Kubernetes Services.
2. Select 'Add' and enter your cluster's configuration.
3. In the 'Authentication' tab, verify that the 'Enable RBAC' setting is set to 'Yes'.
